General Contracting
Comprehensive Project Delivery Managed from a Single Point
General contracting covers the integrated management of all construction activities, from planning and preparation to on-site execution, coordination of different disciplines, quality control, and final handover.
For residential, commercial, industrial, and various other types of projects, site organization, material procurement, construction works, subcontractor coordination, and implementation processes are managed in accordance with architectural, structural, mechanical, and electrical projects.
Each project is managed by evaluating its scope, budget, schedule, technical requirements, and site conditions together.

Advantages of General Contracting
Provides Single-Point Project Management
Different implementation teams and work packages are managed within a single planning system, allowing the project process to progress in a more controlled manner.
Strengthens Coordination Between Disciplines
Architectural, structural, mechanical, electrical, and other application teams are coordinated to help reduce conflicts on site.
Supports Controlled Schedule Management
Construction sequencing, material procurement, and team organization are planned to support progress in line with the agreed schedule.
Facilitates Cost Control
Planning work packages, material requirements, and construction methods at the beginning of the project contributes to more controlled budget management.
Organizes Site Operations
Working areas, team responsibilities, material deliveries, storage areas, and construction sequencing are planned systematically.
Strengthens Quality Control
Construction works are checked at defined stages for dimensions, materials, workmanship, and compliance with the project.
Simplifies the Process for the Client
Instead of managing multiple application teams separately, the project is coordinated through a single main contractor, helping simplify communication and project management.
General Contracting Services

General Contracting Process
Each project is planned individually according to its scope, site conditions, technical requirements, budget, and target completion date.
1. Project and Needs Analysis
The intended use of the project, scope of works, client expectations, and available technical documentation are reviewed.
2. Site Survey
Site conditions, existing buildings, access routes, material delivery areas, working zones, and technical limitations are examined.
3. Preparation of the Work Schedule
Work packages are identified, and construction sequencing, workforce requirements, and estimated durations are planned.
4. Budget and Resource Planning
Material, labor, equipment, and subcontractor requirements are evaluated and project resources are planned.
5. Site Organization
Site layout, working areas, team coordination, material storage, and site circulation are organized.
6. Structural Works
Foundations, reinforced concrete, steel structures, and main building works are carried out in accordance with technical projects.
7. Mechanical and Electrical Works
Infrastructure and installation works are coordinated with architectural and structural construction activities.
8. Roofing, Façade, and Finishing Works
The building envelope, interior applications, finishes, and complementary works are completed.
9. Quality and Implementation Controls
Construction works are inspected at defined stages according to the project, technical details, and application criteria.
10. Final Inspection and Handover
Completed works are reviewed, deficiencies within the project scope are corrected, and the building is handed over ready for use.
Subcontractor Management
In general contracting projects, certain work packages requiring specialist expertise may be carried out by subcontractors.
Their activities are planned according to the project schedule and coordinated with other teams.
Subcontractor management may include:
- Defining the scope of work
- Communicating technical requirements
- Preparing work schedules
- Planning site access
- Coordinating work sequencing
- Managing materials and equipment
- Quality control
- Occupational health and safety requirements
- Inspection of completed works
Material and Procurement Management
Material procurement is an important part of the general contracting process to prevent delays in the project schedule.
Procurement is planned by considering the technical specifications, lead times, storage conditions, and sequence of use of materials.
The following material groups may be managed within the project:
- Concrete and reinforcement materials
- Steel profiles
- Wall materials
- Roofing systems
- Façade materials
